Automatic Barrier Systems

An automatic barrier is an entry control system in which an arm attached to a motorised housing lifts to allow vehicles through. It works with card access, number plate recognition and loop detectors, and is used at car park, residential complex, factory and office entrances. Arm length, opening time and daily traffic volume determine the right model; Pack Door handles installation, card system integration and periodic maintenance as a single provider.

No. The arm does not lower while the underground loop detector and photocell detect a vehicle. This dual-layer safety prevents damage to both vehicle and arm. A rubber impact profile and LED light can also be fitted to the arm tip. During installation, loop detector sensitivity and photocell position are set for the vehicle types, and these safety devices are tested during periodic maintenance.

Yes, an automatic barrier works with an automatic number plate recognition (ANPR) camera that identifies authorised vehicles and raises the arm automatically. Entry and exit records are reported in the software, and time-limited permissions can be set for visitor vehicles. The system can also be managed from a single panel alongside card access, remote controls, loop detectors and property management software.

Yes, barriers with a battery unit continue to operate during a power cut and raise the arm automatically. Without a battery, the arm can be lifted by hand using the manual release key on the housing. A battery module is recommended at residential complex and car park entrances to keep traffic moving, and battery health and charge are checked during periodic maintenance.

Indoor car parks have low ceilings, so an articulated barrier whose arm folds in the middle as it opens is used. This stops the arm from hitting the ceiling or service pipes. Arm length, lane width and ceiling height are measured during the survey, and number plate recognition, loop detectors and card access can all be integrated with this model.
